Abstract

Un aparato para hidroformar una pieza de trabajo hueca para realizar trabajo situadas en una matriz pasando a través de ésta, y que incorpora unmedio para eyectar los pedazos o tapones de material así originados, que utiliza el fluídoh idroformante presurizado como fuerza impulsora para eyectarel pedazo de material creado por un medio para realizar orificios en la pieza de trabajo situada en la matriz, que incluye un punzon movil dispuesto dentrode una perforacion, practicadaen uno de los bloques de la matriz, que abre en la cavidad. Elpunzon incluye un borde cortante en una primera extremidad, quees adyacente a la cavidad. El orificio es formado cuando el punzon es insertado contra una pieza de trabajo huecaposicionanda en el aparato, con lo cual secrea un pedazo o tapon de material. El medio eyector del pedazo de material, incluye dos pasadizos formados internamente en el mismo bloque de matris quetiene el medio para realizar orificios en una piezade trabajo si tuada en la matriz. Los pasadizos se extiendenen una direccion genereal transversal conrespecto a la perforaciom, estando un primer pasadizo en comunicacion, con la fuente del fluido hidroformante y el segundopasadizo situado enforma opuestaal primero, para formar un canaclonj para capturar el pedazo de material eyectado por el fluido hidroformante suministrado al primer pasadizo, solamentedespués que la pieza e trabajo ha sido hidroformada y permanece presurizada y el punzon ret raido.An apparatus for hydroforming a hollow workpiece to perform work situated in a die passing through it, and incorporating a means for ejecting pieces or plugs of material so generated, which uses the pressurized idroforming fluid as a driving force to eject the piece of Material created by a means for making holes in the workpiece located in the die, which includes a mobile punch arranged inside a perforation, made in one of the blocks of the die, which opens in the cavity. The punch includes a cutting edge at a first end, which is adjacent to the cavity. The hole is formed when the punch is inserted against a hollow workpiece positioned in the apparatus, thereby sectioning a piece or plug of material. The ejector means of the piece of material includes two passageways formed internally in the same matrix block that has the means for making holes in a workpiece placed in the die. The passageways extend in a general transverse direction with respect to the bore, with a first passage communicating with the source of the hydroforming fluid and the second passage opposite to the first, to form a channel to capture the piece of material ejected by the supplied hydroforming fluid. to the first passageway, only after the workpiece has been hydroformed and remains pressurized and the punch removed.
